Severe Morning Sickness and Depression

I’m 13 weeks pregnant with baby number two and really struggling with daily life right now. I have a very stressful job (emotionally and physically) on top of taking care of a toddler. I have felt like I’ve had the flu for the entire three months I’ve been pregnant now. I finally found some medication that seems to help a little with with my morning sickness but it never completely goes away. I’m struggling to stay afloat mentally. My husband is getting very frustrated with me because I’m not staying on top of laundry and other daily house hold chores. I feel horrible for not keeping up with my share of things but I’m not sure how to stop feeling like this. He says that I need to try harder to push myself out of this depressed mindset by exercising but it feels really hard to even find the energy to do day to day life right now. I could really use some advice and/or support right now. 😔
